Title: Fingerprint image processing system capable of simply processing minutiae
Inventor: OMORI RITSUKO
IPC: G07C9/00
Filed: 1992-04-02
Granted: 1996-07-16
Abstract: In a fingerprint image processing system for use in processing a fingerprint image prior to identification of a fingerprint, edition or correction is made by adding true minutiae and/or eliminating false minutiae from the fingerprint image displayed on an output device to leave only real minutiae and to formulate a minutia list which registers a location of each minutia, a minutia direction, and minutia relations representative of adjacent minutia pairs.  Edition of the minutiae may be carried out by handling the minutiae as an image while correction may be made by recognizing the minutiae as data.  Ridge numbers between two adjacent ones of the minutiae are included in the minutia relations and may be manually or automatically extracted from the fingerprint image.

Granted: 1997-02-04
Abstract: A connection for adjustably holding two window hardware members in pivotally connected relationship, in-cluding a first hardware member with a first cylindrical opening, a second hardware member with a second cylindrical opening, and a stud.  The stud has a flange having two sub-stantially parallel faces and a peripheral surface therebe-tween, with a rivet portion projecting from one face and a pivot portion projecting from the other face.  The rivet portion includes a cylindrical neck extending through the first cylindrical opening and a head on the end of the neck, the flange and the head engaging opposite sides of the first hardware member to frictionally secure the stud against pivoting relative to the track.  The pivot portion includes a cylindrical shaft eccentric from the cylindrical neck and extending through the second cylindrical opening. A C-ring is disposed in an external peripheral groove in the pivot portion to secure the second hardware member thereto for pivoting about the cylindrical shaft.  A part of the C-ring is in the peripheral groove and a part ex-tends radially beyond the pivot portion periphery when the C-ring is in a securing position.  The peripheral groove has a depth to enable deformation of the C-ring by movement of the spaced-apart ends towards each other to a release position in which substantially all of the C-ring is in the peripheral groove.  The stud flange peripheral surface is engageable with a tool to allow for adjustment of the piv-otal connection by pivoting the stud.

Abstract: A case for cosmetics including a cover and a base. The cover and base have end and peripheral walls which together define an interior compartment. An integrally formed latching device is located in the front portion of the case. The latching device comprises a push tab in the form of a tongue-like section of the base peripheral wall. The distal and intermediate portions of the push tab are separated from adjacent portions of the base peripheral wall by at least one slot which extends alongside the push tab to its proximal end. Coacting cam means associated with the push tab and with an adjacent portion of the cover produces a force biasing the front portion of the base and cover apart when the push tab is moved inwar-dly with the latch engaged. Interengagement means is in-tegrally formed on the cover and base peripheral walls to latch the cover to the base when the front portions of the base and cover are pressed together and unlatch when the front portions of the base and cover are forced apart.

Abstract: A paper mask device in which the position of longitudinal masks can be changed without damaging a web of printing paper.  When it is changed from the borderless printing to the printing with border, one ends of the longitudinal masks are moved inwardly toward each other by means of a first transfer unit while keeping the other ends overlapped on the edges of the printing paper.  A second transfer unit then operates to move the other ends of the longitudinal masks inwardly to set the width of the print size.  The longitudinal masks can be overlapped on both edges of the printing paper without damaging it.

Title: Fuselage burn-through blocking material
Inventor: SCHAEFER WERNER
IPC: B32B19/06
Filed: 1995-03-21
Granted: 2000-11-07
Abstract: A fuselage burn-through blocking material includes a layer of a 30 to 300 g/m non-woven material of needled, flame retardant fibres laminated to one or both surfaces of a 100 to 600 g/m mica paper. Mutual attachment of the layers in the laminate isachieved by a partially cross-linked, latently adhesive, heat resistant binder included in the mica paper itself. The process for manufacture of the laminate includes adhesiveconnection of the layers under pressure and at a temperature which does not trigger full cross-linking of the binder. The resulting two or three layer laminate when installed in a fuselage significantly increases the fuselage burn-through time in a post-crash fire to at least 3 minutes.
